"He's just exhausted," a source told TMZ of West's reasoning for the cancellation.

The artist went on a political rant on stage in San Jose last week, in which he said he didn't vote in the presidential election but that he would have voted for President-elect Donald Trump. The admission garnered mixed reactions from West's fans.

West then turned his attention to racism. "If people are racist and they feel more inspired to say how they feel, then they're exposing themselves, bro," he said. "This is what I'm saying. It's already the beginning of change. Sometimes things that you might think are bad might have to happen in order for change to f---ing happen."

On Saturday, West abruptly ended his concert in Sacramento after performing just three songs.
